new bios for x1800xt

[ic3m4n2005]

According to this hole thread, which card should i buy now to get some "positive" results ?

[maxxxpct]

new bios
cpu fx55 san diego 3020mhz ram vitesta 600 timing 2.5/3/3/6 232x13
scheda sapphire x1800xt
freq 762/918
watercooling cpu/vga

Those are amazing clocks maxxpt, but system mem bandiwth is holding you back there. SHould be getting at least 11500 with those clocks. Is that with a divider or 1:1 on your fx?

Ok... now I've checked temps while playing and it was 80... put the coller max and temps were 57

Does anyone use RivaTuner?
If so what are your volt readings with stock and XTPE bios?
Im at 1,3V in 2D and 1,4 with stock and 1,48 XTPE in 3D mode.
And what would be the max safe voltage?

[Quigs]

I decided to be stupid tonight and flash my XL with an XT bios. I did not use the PE bios floating in this thread. Here were the not so good results.

Upon reboot the screen went black - nothing. I ended up turning the system completely off and rebooting. That worked - system booted into windows and it began displaying that it found new hardware. It did not find acceptable drivers and prompted me for them. I selected to let it find them - it did not. I then re-installed the 5.12 drivers - no luck. Loading ATItool confirmed the bios was different - clocks were now at 600/700 except ATItool did not recognize the card. So, I could not check the voltages. Windows was still using the base VGA driver so things were a little clunky. I did not do any benching because of this.

Under the control panel/system/hardware it showed unkown ? hardware.

I reloaded the bios flashing tool - it said I had an ATI 520 installed. I forced a reflash to my saved XL bios. That worked and a reboot put me back to normal. A little risky - but worth the try.

At least I am back to normal. Not sure what I was thinking. I would have tried to XT PE bios in this thread, but I know the card can't touch 800 mem with those stock volts.

Thanks for trying. Took a lot of balls to do what you did. I know I would have freaked out getting a black screen after a flash. I am glad you got it all working again though.

Not sure what I was thinking (maybe my thought was I could explain it to my wife that my card simply died and that I needed to buy a new XT to replace it). I went in there to simply back up my current bios. I could not resist trying. Funny thing is I held my mouse over the proceed button for a minute - finally said what the hell. Black screen made me sick. Not sure why it did not work. I have a Sapphire card - but it merely has the sticker slapped on it.

One other interesting point. There is mention that you have to set your card to 500/500 before flashing - after flashing to the XT bios, I tried that. Teh screen went bright orange and the system froze. Not a good feeling. Luckily it booted and I left the clocks at 600/700 and the reflash worked.

did you use atitool or overclock, to underclock. as overclock won't work for everyone.

Flashed sapphire to PE, done 3dmark05 at 9451 at 760/800 my CPU is holding me back though.
2400mhz sigh.

Seems stable though but me on watercooling mcw50 and temp now is 41c, and goes to around 52 or so when benching.

more mhz on your cpu will help a lot. also you need to tweak your ram
i got
10234 729/1620 at 2800mhz with standard bios AIR
9830 700/810 at 2500mhz with the new bios AIR

So you flashed a 256DDR XL card to a 512DDR XTOC Version? That is nuts!! LoL

I actually decided to stretch my luck tonight. I tried 3 different XT bioses. One original, one the PE version, and on XT 256mb version - non of them worked on my XL. All booted fine into windows. The clocks were set to 595/695 or somewhere close to that. It was using the VGA driver as windows could not recognize the card. As with before, a reinstall of the ATI drivers did not do anything.

Looks like with my Sapphire X1800XL card it is a no go for an XT bios. Fun giving it a try - living on the edge. Not sure if it was my card or not, or what prevented it from working. At least I got back to a normal state. Stupid stunt, but now people know the answer.

I got finally installed my wc block, so here it is in pics:

Naked card

Naked core

And finally installed

Temps are now 41c idle and 47c while gaming (from ATITool) and clocks are now at the stock clocks.

zalaman... now that's extreme dude

why did you chose the zalman ?

Why not? Works just fine though it's Alu-block. And it wasn't so expensive

not afraid of oxydation-reduction ?

btw, just recieved my WC (1a SL3 + 2 alphacool 7800/x1800 WBs ^^ )

Nope

it's better use the additive for water if you use 1A- cooling... It's not a Low profile watercooler, it's use micro - canal in the waterblock.. if you don't careful with this, your cooling-perf can be reduce dramatically. or use Ethanol + anti freeze as liquid.


One ask about bios. Is the max limit in CCC overdrive have increase? ( limit is fixed by soft at 690/800, can you use it now for set at more..)

[dnottis]

Works great here so far!! I dropped to 500 / 500 before the flash.

[dnottis]

Ok here are my findings - I was using CCC at 690 / 780. I could not run the memory at 800 stock volts or it would artifact. I was also breaking 10,000 in 3dmark 05, I believe 10,090. - (Nope 9803 with stock bios 690 / 780 - sorry)

So I flashed to this bios, 690 / 800 is stable, 3dmark 05 dropped to 9942 and I can run 800 memory no problem. I believe this bios slackened the memory timings a bit to make it more stable. Thats fine but I dropped slight performance at the higher oc. I prefer this however since it's not a software OC and the fan seems to spin faster than when OC'd in the CCC.

I gained 1 FPS Avg. in Fear however!!

BTW performance in gaming is outstanding!!
